I have the system described below overclocked to 45x100 and am prime95/large FFTs now to test for stability. I didn't do a whole lot of tweaks but I do want to share the settings I am currently testing and get feedback:

1) Others settings I should tweak?
2) Are these values sane?
3) Recommendations to lower voltages?

P8Z77-V Pro/BIOS 1206
3370K @ 45x100 MHz
2x8 Gb GSkill Ripjaw 9-9-9-24 @ 1600 Mhz
NH-D14 HS

Under AI Tweaker>CPU Management:
Code:
CPU Voltage = 1.300
VCCSA Voltage = 0.92500
CPU PLL Voltage = 1.81875
PCH Voltage = 1.06000
Under AI Tweaker>DIGI+ Power Control:
Code:
CPU Load-Line Calibration = Ultra High
CPU Current Capability = 140 %
CPU Power Response = Medium
Temps with case open (still cleaning up wires) are pretty steady across all cores @ 73-77 while running large FFTs.
